Going to a higher radar frequency band
mitigates the effect, but this involves design tradeoffs.
In this respect, it is now imperative that worldwide weather services as well as radar operators and manufacturers proactively involve themselves in the radio frequency management process and work in close contact with their national radio authorities to ensure that meteorological interests be duly taken into account in any decision-making process toward the future usage of any wireless devices (such as RLAN) within or close to weather radar frequency bands
. One easy starting point would be to show this article to the spectrum regulator.
Future wind farms maybe constructed with new materials that are less reflective in radar frequency bands
. But this trend will not change the nature of the problems that turbines potentially cause to radars.
The sea clutter change pattern libraries for three radar frequency bands
(S, C, and X) are shown in Fig.
In response to the needs of civil and military radar manufacturers, single bipolar transistors capable of producing 300 W of pulsed RF power have been developed for the more common radar frequency bands
. The devices are designed specifically for class C operation.
The advantages of the lower radar frequency bands
are clear, and as solid-state devices attain higher efficiencies and power levels they will supplant tubes as RF sources.
